Yes. Some red food coloring is made from crushed insects and vegans do not eat it. There was a big story about it when it was discovered that it was used in a Starbucks drink.
All the universe is divided into animal, vegetable and mineral. Insects are not vegetables or minerals so they have to be animals. ("Animal" means "moving".)
Of course. That is their big terror. They are terrified that some insect larvae will end up in their denatured, denuded, cornflakes or whatever they are allowed to ingest.
I have seen so many Vegan wannabe's that have zero clue. One guy at my school was eating crackers because he couldn't figure out a pure enough food. So that is what he ate. Some health nut. Just a nut. Many of them are.
I mean are bacteria animals? Because they are living forms of what insects look like on a microscopic basis and they cannot be denied. They are in your body already.
So chill vegans.
We have enough conflict with the eating of animals that can think and feel pain. Keep it simple. Don't eat those.
